What Multiaqua, Inc. does

Multiaqua, Inc. is a privately held manufacturer of ducted and ductless air-cooled hydronic chiller systems founded in 1999 and headquartered at 306 Hagood Street in Easley, South Carolina. The company designs and builds chillers (MAC series in 3, 4, and 5-ton capacities using R32 or R407c refrigerants, plus the MHRC2 simultaneous heating and cooling chiller) and a broad companion line of hydronic fan coils and air handlers in universal-mount, ceiling-concealed, cassette, and hi-wall form factors. Core technical differentiators include Copeland Scroll compressors, brazed plate heat exchangers, common off-the-shelf service components, BAS/BACnet readiness, and an architecture that keeps the refrigerant circuit outside the conditioned structure — eliminating in-wall refrigerant handling and ductwork.

Multiaqua sells exclusively through a B2B channel-partner model, distributing equipment to over 715 independent contractors and distributors across all major US regions via a 'Find a Pro' locator tool; technical support, warranty, and parts fulfillment are outsourced to a separate entity, Aqua-Parts LLC. The company also markets directly to contractors and end-customers through an extensive library of technical submittals, application brochures (residential, commercial/industrial, indoor growing, lodging), and the proprietary HSS Hydronic System Design software. Certifications include ISO 9002, UL Standard 95, and AHRI compliance. Customer segments span residential, light commercial, hospitality, indoor growing (controlled environment agriculture), and industrial process cooling. Maria Feria serves as Vice President; no institutional ownership, funding history, or financial disclosures are available in the source material.

Core offering

Multiaqua manufactures and sells air-cooled hydronic chiller systems in 3, 4, and 5-ton capacities, paired with a broad line of ductless hydronic fan coils (universal, ceiling concealed, cassette, hi-wall, and air handler form factors) and supporting accessories such as pumps, valves, tanks, and thermostats. Equipment is distributed through a U.S. network of independent distributors and contractors for residential and commercial HVAC installations, with parts and technical support handled by Aqua-Parts LLC.

Product overview

Multiaqua, Inc. is a manufacturer of ducted and ductless air-cooled water chiller systems for commercial and residential markets. The product portfolio centers on chilled water air conditioning systems consisting of air-cooled chillers (MAC series, MHRC2 heat recovery chiller) paired with a comprehensive line of hydronic fan coils and air handlers. The chillers are available in 3, 4, and 5-ton cooling capacities using R32 or R407c refrigerants and feature Copeland Scroll compressors. The fan coil lineup includes multiple form factors: universal mount (CFFWA/CFFWA4P), air handlers (CWA2/CWA4), ceiling concealed (MCCW, MHCCW, MHNCCW), cassette (MH1WC4W, MHCFC4W), and hi-wall (MHQWW) units. The MHRC2 offers simultaneous heating and cooling capability. Accessory products include bypass valves, circulating pumps, condensate pumps, tanks, thermostats (including BACnet-enabled), and zone valves. Key differentiators include no refrigerant handling requirements, no ductwork needs, zero line length limitations, and zoned cooling capability. The company operates from Easley, South Carolina.
